The Humble Bundle has evolved. No, not into a Wartortle - the charitable pay-what-you-want initiative is set to get humbler and bundlier and even more regular with the announcement of The Humble Weekly Sale , which will offer a new game for your consideration every Tuesday. The first deal goes live now, with the wonderful Bastion. As ever you can pay what you want for a DRM-free copy of the game (on Windows, Mac and Linux), though a donation of $1 or more will also get you a Steam key. If you beat the average you'll get extra digital content; spend $25 or more and you'll get physical merch thrown in too, including an actual Bastion bandana. Just the thing for when you wake up in a world of floating islands, with Logan Cunningham narrating everything you do.

Here's the full list of additional gubbins. Pay over the average to unlock:
